Never seen one of these: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1476893365 I won't put it down since I've never seen/heard one. I'm all for alternative materials IF they are a good thing. Of course I also missed the advent of Fiberglas double basses, though sadly did have a white plastic sousaphone inflicted upon me. I rebelled and carried a brass one despite its extra weight. I still feel that familiar ache in the shoulder on cool and windy Fall days.
